Insulation system and method for buildings

Abstract

An apparatus, method and system of insulating a building such as a poultry barn uses netting structurally of the type to hold sod together. The netting is stapled to the bottom of trusses making up the ceiling of a barn and the attic of the barn. Ceiling material is superimposed below the netting to form a ceiling. Loose insulation, typically fiberglass, is blown onto the netting to be held thereby and to form an insulation layer in the attic of the barn.

What is claimed is: 
     
       1. A method for placing loose insulation in an attic of a building having a plurality of trusses with bottom surfaces making up a bottom surface of the attic of the building, comprising:
 attaching mesh netting to the bottom surfaces of the plurality of trusses making up the bottom surface of the attic of the building; 
 installing ceiling material below the mesh netting, the ceiling material comprising a woven ceiling material, and further comprising stapling the woven ceiling material to the plurality of trusses to which the mesh netting is attached; and 
 blowing loose insulation onto the mesh netting which is attached to the plurality of trusses, said mesh netting having openings sufficiently small to prevent blown loose insulation from passing through the mesh netting, and for capturing the blown loose insulation to prevent migration of the loose insulation. 
 
     
     
       2. The method of  claim 1 , wherein said loose insulation comprises fiberglass wool. 
     
     
       3. The method of  claim 1 , wherein said mesh netting has a strand count which comprises:
   13.2+/−2 per 10″ MD,  
 
   7.0+/−0.5 per 10″ TD.  
 
 
     
     
       4. The method of  claim 1 , wherein said building comprises a poultry barn. 
     
     
       5. The method of  claim 1 , wherein said mesh netting is stapled to the plurality of trusses in a manner wherein said mesh netting sags sufficiently that said loose insulation is retained thereon, while allowing the ceiling material to be installed to function as a ceiling. 
     
     
       6. The method of  claim 5 , wherein about 10 percent of mesh netting overage is provided to achieve controlled sagging of the mesh netting when stapled to the plurality of trusses. 
     
     
       7. The method of  claim 6 , wherein when said ceiling material is installed, the mesh netting is exposed to the attic of the building. 
     
     
       8. The method of  claim 1 , wherein said mesh netting is non-biodegradable.
